The Science Behind the Body's Response to Exercise

The video explains how exercise increases the body's energy demand, requiring more glucose and oxygen for cellular respiration. It describes physiological responses like increased breathing and heart rates to supply muscles with oxygenated blood. When oxygen is insufficient, anaerobic respiration occurs, producing lactic acid and causing muscle cramps. The video also discusses oxygen debt and muscle fatigue resulting from intense exercise.
